| 摘 要： | 利用且末县近50a的气象、水文、社会经济数据，分析了多年来且末水资源及其各影响因素的变化情况，结合相关分析、主成分分析对影响水资源变化的各因素进行定量分析，结果表明：近50a来且末水资源总量变化不大，但年变幅度较大；年均降水量和年均气温有上升的趋势，人类活动频繁。主成分分析后得到两个主成分，累计贡献率可达80％以上，第一主成分可解释为人为因子，第二主成分可解释为气候因子，说明人类活动对水资源的影响远大于气候变化的影响。图7，表3，参13。

| Abstract: | In this article,the change of water resources and its related factors during the 50 years in Qerchen County were studied by applying the method of both correlation and principal component analysis via using the meteorological,hydrological,and socioeconomic data. Results indicated that during the past 50 years the total water resources of Qerchen county did not occur dramatic change while annual change of it is obvious. At the same time,human activities are more frequent and average annual precipitation and ... |
